Cooling Air Flow Experiment
 

With the hood closed, run the engine at a fast idle. Pass a piece of paper towel lengthwise along the louvers in the hood. Note how the towel moves. There will be interesting variations in the air flows.

So?

Katy, I have no conclusion or recommendation for my post. It's just something to do. Have you tried it?

Re: Cooling Air Flow Experiment
 

Haven't tried it, don't intend to., don't see any need for it, car cools fine the way it is.

With my hood off the air flows backwards at an idle, radiator upper corners ?! I covered the radiator trying to warm it up faster and the towel blew from the radiator. Weird things happen

Re: Cooling Air Flow Experiment
 

Perhaps your test would show something with and without the engine pans?

Re: Cooling Air Flow Experiment
 

My thought too.

Re: Cooling Air Flow Experiment
 

Use of an infrared heat gun test device over the face of a radiator will show fairly uniform temps at various sections on a very good one. Most radiators will show a mix of hotter and cooler spots.

Katy, you miss the point of the experiment, that is to try something for fun and perhaps learn something.



Yes, the air flow changes when there are no engine side pans installed.

Some people have way too much time on their hands - Stop thinking.

I don't see what this experiment tells you. A better experiment, if possible, would be to do this same experiment at 40 MPH with the engine pans in place to see the ACTUAL airflow while cruising.

I see in my mind an array of pitot tubes and a bank of manometers in the cab. Also needed is a clip board and someone to sharpen pencils.

I have to agree with Bob. He's in cold New York and I'm in cold Ohio. We can't drive 'em in the winter so we play with them. Keeps the mind active. Mine cools fine too but why not experiment and learn?

Thanks Marty In Ohio!

Guess those of us where we get cold/snow get cabin fever and want to drive our cars!
